RITE.

Specification of Letters Patent.

Application filed July 11, 1917. Seria1No.179,923.

' to an aeroplane, and which, when descending will sail down smoothly and easily without dan er of breakage,

Another object is to provide a kite of this character which is so constructed as to adapt it for use for scientific purposes for advertising and as a high grade toy.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that'changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure-1 represents a perspective view of a kite constructed in accordance with this invention, and

Fig. 2 is a longitudinal section thereof.

In the embodiment illustrated, the kite constituting this invention comprises a pair of vertically spaced front planes 1 and 2 and a pair of vertically spaced rear planes 3 and 4; connected by a rigid keel 5, it being understood that the keel extends longitudi nally of the kite and the planes transversely thereof, said planes'pro ecting at opposite ends on opposite sides of the keel. This keel 5 is V-shaped in cross -section and-tapers toward its rear end and is composed of a light framework comprising side bars 6, end bars 7 anda ridge pole 8. A light weight cloth 9 of any suitable fabric is stretched over this frame from one side bar 6 to the other around 'the ridge pole 8 as is shown clearly in Fig. 1, the ends of the keel being left open.

The front planes 1 and 2 each. comprises a substantially rectangular frame composedof side bars 10 connected by end bars 11 and which have light weight cloth 12 stretched thereover. Posts 13 connect the frames of the two planes 1 and 2 at their corners as is shown clearly in Fig. 1 and an upright 14 is secured atone end to the front end of the ridge pole 8 and is fixed to the side bars 10 of the two front planes at a point midway their length, said upright Patented Apr. 2, 1918.

projecting above the upper plane 1 and having a bracing wire or cord 15 attached thereto midway its length, the opposed ends of said cord being secured to the front corners of the upper plane 1.

Tightening and bracing cords or wires 16 and 17 are secured to the front corners of plane 2 and extend up and are attached to the upright 14: at its junction with plane 1' and these cords are tightened sufliciently so as to cause the opposite ends of both the lower and upper'planes to curve upwardly to facilitate the passage of the kite through the air and to adapt it to ride horizontally. Bracing cords or wires 18 and 19 are attached at their opposite ends to the front corners of the plane 1 and extend downwardly and are connected to the front cross bar of plane 2 at its junction with the upright 14 and these wires counteract the strain caused by wires 16 and 17,

The rear planes 3 and 4 are constructed of similar frames to those constituting the front frames and are connected by corner posts 13, said planes 3 and 4 being shorter than planes 1 and 2 and are preferably about one-half the length thereof, the keel 5 which extends longitudinally throughout the entire length of the kite being preferably made the same length as the front planes, 1' and 2. Longitudinal brace bars 20 also connect the front and rear planes, being here shown connected with the rear upper plane 3 at its rear edge and with the front upper plane 1 at its front edge. Bracrear plane 8' with the rear side bar of the V .lower front plane 2 at points adjacent the side bars 6 of the keel as is shown clearly in Fig. 2.

Other bracing wires 23 also, connect the front side bar of theyupperrear plane 3 with therear side bar of the lower front plane 2 and similar wires 24 connect the front side bar of the rear lower plane 4: with the rear side bar of the upper front planel.

The front portion of the keel between the side bars 6 is preferably braced by cross wires 25 which assist in imparting rigidity to the keel.

A rudder 26 is carried by the rear end of the kite and has one arm 27 thereof extended between the upper and lower rear planes 3 and 4:, while another arm 28 extends under the rear end of keel 5 and is attached thereto at a point in advance of the rear terminal of said keel and operates to steer the kite until it has ascended for a couple of hundred feet and after it reaches this point, the other portion of the rudder will take care of the steering thereof because the kite then lies horizontally in the air.

A bridle 29 is connected at one end to the rear end of the keel as shown at 30 and at its other end to the front end of said keel as shown at 31 and a single cord 32 is fastened to the front end of this bridle and may be of any suitable or desired length according to the distance it is desired that the kite shall ascend.

The keel 5 is also preferably provided midway its ends with a bracins strip shown in dotted lines at 5 in Fig. 2 which adds to the rigidity of the keel.

While the frame of this kite is preferably constructed of pine sticks, it is not limited to any such material, as aluminum or any suitable light weight material may be employed for this purpose and the fabric which is stretched over the planes, may be of canvas or any other suitable material, it being understood that both pairs of planes are left openat their opposite ends as is shown clearly in Fig.- 1.

The ends vof the vertically spaced front f planes 1 and 2 are preferably braced by cross wires 33 while similar cross wires 34 are arranged at the ends of the rear planes.

While this improved kite is especially designed as a high class toy, it is to be understood that it may be used for advertising purposes, carrying the advertisements on panels depending therefrom or attached thereto in any suitable manner.

From the foregoing description, taken in connection with the-accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which.

1. A kite of the class described comprising a keel V-shaped in cross section, a pair of vertically spaced front planes secured to the upper edge of said keel and extending transversely thereof on opposite sides, a rear planesecured to the upper edge of said keel and extending on opposite sides thereof,

bracing means between said planes, and a rudder carried by the rear end of said keel and having an arm extending under the keel.

2. A kite of the class described comprismg a keel V-shaped in cross section-and tapering toward its rear end, a pair of substantially rectangular planes arranged transversely across the front end of said 'keel on its upper edge, a similar pair of planes arranged across the rear end of said keel, bracing means between the planes of each pair and between the two pairs, and a rudder carried by the rear end of said keel.
